LPG Leakage Detection Circuit Breaker Using RF Module

LPG Has A Dangerous Characteristics That Can Be Considered, TheStatement of The ProblemSignificance of The StudyAnother Related Project Paper to This Project Is Design andin This Project The Microcontroller Is Used as The Software Programs toThe Transmitted Data Is Received by An RF Receiver Operating at TheEncoder & RF TransmitterThe toxicity, LPG gas even though slightly toxic, is not poisonous it can pose a serious effect if they leak, it may leak as a gas or a liquid. If the liquid leaks it will quickly evaporate and form a relatively large cloud of gas which will drop to the ground, as it is heavier than air. LPG vapors can run for long distances along the ground and can collect in drains or basements cylinders can explode if involved in a fire. The health impact this dangerous gas can cause cold burns to the skin and it can act as an asphyxiate at high concentrations. Leak cause a negative effect to the health such that the hydrocarbons and other chemicals of the LPG causes very long sleep. It also causes irritated respiratory tract, nose and eyes. fIntroductionGet price
